Introduction

The Atlona AT-OPUS-RX41 is a 4×1 switcher and receiver for 4K high dynamic range (HDR) formats. It features three HDMI inputs, plus an HDBaseT input for receiving video, embedded audio, control signals, power, and Ethernet over distances of up to 330 feet (100 meters). Supporting 4K/UHD @ 60 Hz with 4:4:4 chroma sampling, as well as HDMI data rates up to 18 Gbps, the OPUS-RX41 is the perfect complement to an Atlona Opus™ Series matrix switcher in whole-house AV applications allowing display of 4K HDR content from either the matrix or one of the connected local sources.

The OPUS-RX41 includes a number of key features to help simplify residential deployments. Extension of CEC, IR, and RS-232 signals over HDBaseT allows a control system connected to the OPUS-RX41 to select inputs on the matrix or control its sources, and allows the matrix to control the local room display. A handheld IR remote control is included for power and input selection on the OPUS-RX41. Advanced HDMI Audio Return Channel (ARC) routes audio from a smart TV to both the local TOSLINK connection as well as HDBaseT. EDID management, selectable 4K to 1080p downscaling, and HDCP 2.2 support with selectable down-conversion to HDCP 1.4 ensures compatibility with legacy displays. Remote power allows the device to be powered by an Opus matrix switcher, for installation flexibility at a display or projector.

IP Configuration

The AT-OPUS-RX41 is shipped with DHCP enabled. Once connected to a network, the DHCP server (if available), will automatically assign an IP address to the unit. Use an IP scanner, along with the MAC address on the back of the unit, to identify both the unit and its IP address on the network. If a static IP address is desired, the unit can be switched to static IP mode. Use one of the following procedures to switch between DHCP and static IP mode. The default static IP address of the AT-OPUS-RX41 is 192.168.1.254.

If the AT-OPUS-RX41 is unable to detect a DHCP server within 15 seconds, then the unit will set all IP settings to zero.

Setting the IP Mode

1. Make sure the AT-OPUS-RX41 is powered.
2. Connect an Ethernet cable between the LAN port of the AT-OPUS-RX41 and the Local Area Network (LAN).

1. Press and hold the INPUT button on the front panel for approximately 20 seconds. Release the INPUT button once the POWER button begins to flash blue and red. The number of flashes will indicate the currently selected IP mode.

Web Server Login

The AT-OPUS-RX41 includes a built-in web GUI. Atlona recommends that the Web Server be used to set up the AT-OPUS-RX41, as it provides intuitive management of all features.

The AT-OPUS-RX41 is shipped with DHCP enabled. Once connected to a network, the DHCP server will automatically assign an IP address to the unit. Use an IP scanner to determine the IP address of the AT-OPUS-RX41. If a static IP address is desired, refer to IP Configuration (page 16). The default static IP address of the AT-OPUS-RX41 is 192.168.1.254.

1. Launch a web browser.
2. In the address bar, type the IP address of the AT-OPUS-RX41.
3. The Login page will be displayed.

1. Type admin, using lower-case characters, in the Username field.
2. Type Atlona in the Password field. This is the default password. The password field is case-sensitive. When the password is entered, it will be masked. The password can be changed, if desired. Refer to the Config page (page 39) for more information.
3. Click the Submit button or press the ENTER key on the keyboard.

Auto Switching

Auto-switching can also be used to automatically select an input. Auto-switch is enabled by default and must be enabled for this feature to work. When auto-switching is enabled, the AT-OPUS-RX41 will automatically switch inputs, based on the presence of an input signal. Enable auto-switching by using one of the following methods.

Using the Web Server

1. Login to the Web Server and access the A/V Settings page (page 35).

Physical Input Switching

1. Connect a source to any of the four input ports on the rear panel. The AT-OPUS-RX41 will automatically switch to the port with the connected source. The following rules apply to auto-switching.

• If a source is disconnected, then the AT-OPUS-RX41 will fallback to a port with an active source.
- If all sources are disconnected, then the AT-OPUS-RX41 will retain the port of the last-connected source.

NOTE: The AT-OPUS-RX41 retains the currently selected input, even after the unit is powered-off then powered-on.

Scaler Pass-Through

Click this toggle switch to enable or disable the scaler pass-through feature. When set to the OFF position, 4K content will be down-scaled to 1080p. When set to the ON position, the output resolution / timing will be the same as the input source. The default setting is OFF.

IMPORTANT: The scaler will only downscale the image resolution and does not support frame rate scaling/conversion such as 60 Hz to 30 Hz. The frame rate of the source must be supported by the display device.

1. Login to the web server. Refer to Web Server Login (page 20) for more information.
2. Click A/V Settings in the menu bar.
3. Click the Scaler Pass-Through toggle switch to the ON position to maintain the same resolution on the output, as the source.

1. Click the toggle switch again, to return the Scaler toggle to the OFF (default) position, and allow downscaling of 4K content.

Refer to the next page for more information on scaling.

Notes on Scaling

The following section provides important information about how the AT-OPUS-RX41 processes 4K (UHD) video signals.

• The HDMI OUTPUT port supports up to 4K @ 60 Hz, 12-bit, with HDR.
- If the source is 4K, and the HDMI OUTPUT port is connected to a 1080p (not 4K-capable) display, then the output will be down-scaled as follows:

Input Output

4K @ 24 Hz 1080p @ 24 Hz

4K @ 30 Hz 1080p @ 30 Hz

4K @ 60 Hz, 4:2:0 1080p @ 60 Hz, YUV/RGB 4:4:4

• HDR / Dolby Vision / HLG formats cannot be down-scaled to 1080p. If the source content has HDR, then the color saturation on the video output my appear "washed out".
• The internal scaler will be bypassed if the connected display supports the resolution and timing information from the source device.

HDCP Settings

Normally, if a source is transmitting HDCP content to a display that is not HDCP-compatible, then the resulting image on the display will result in "snow", image flickering, or no picture.

For example, in the illustration below, a laptop source is connected to the AT-OPUS-RX41. A non-compliant display is connected to the AT-OPUS-RX41 using an HDMI cable.

graph LR
    A["Non-Compliant Display"] -->|USB| B["AT-OPUS-RX41"]
    B -->|H2048| C["Laptop"]

By default, the laptop may transmit HDCP content. However, when connected to a display that does not support HDCP, the laptop must be instructed to send non-HDCP content, in order for the content to be displayed.

1. Open the desired web browser and enter the IP address of the AT-OPUS-RX41.
2. Log in as the admin user with the required credentials. The factory-default username and password for the admin user are listed below:

Username: admin

Password: Atlona

1. Click A/V Settings in the menu bar.
2. Click the drop-down list, next to the HDMI input that is connected to the source, and set it to the Noncompliant. This will instruct the source device to send non-HDCP content, if possible. In the example below, the source is connected to Input 2 and the connected display does not support HDCP content.

HDCP Settings

Input 1

Automatic

Input 2

Noncompliant

Input 3

Using the Audio Return Channel (ARC)

The Audio Return Channel (ARC) allows audio to be sent upstream, from the display device, to the AT-OPUS-RX41 over an HDMI cable. The audio can then be output over the OPTICAL port or sent over HDBaseT, back to the matrix. This technique can be used to send audio from a Smart TV, in case the content originator is the TV, to an A/V receiver, providing a multichannel audio experience. The advantage of ARC is that no additional audio cables are required to be connected between the display and the audio output device.

The illustration below, shows an example of how the Audio Return Channel works. The dark green lines identify the audio coming from the display. The instructions on the following page will reference the diagram below.

NOTE: Some displays limit ARC to 2-channel audio. Refer to the documentation that came with your display for more information. When ARC is enabled, the HDMI inputs will be disabled. To reactivate the HDMI inputs, ARC must be disabled. Refer to Switching between ARC and HDMI inputs (page 28) for more information.
